TRANSFER-CYLINDER HAND-PRESS.

SPECIFICATION forming' part of Letters )Patent No. 783,188, dated February 21, 1905.

Application led September 2, 1904. Serial No. 223.116.

To (tI/Z wfbom/ it may concern:

Be it known that I, ALBERT J. FORD, a citizen of the United States, residing 1n New York, borough of Manhattan, in the State of New York,have invented certain new and useful Improvements in Transfer-Cylinder Hand- Presses, of which the following is a specification.

This invention relates to an improved cylinder-transfer press which is manually operated and by means of which a print is made from a stone, aluminium, or Zinc plate or any other printing-surface directly onto a rubber blanket on the hand-operated cylinder and then transferred to the board, plate, or other article to be printed by rolling the cylinder over the same. After the impression has been transferred in this mannerthe cylinder is returned to its initial position for making the next transfer, and so on; and for this purpose the invention consists of a transfer-cylinder hand-press which comprises a supportingframe, plate and work supporting beds supported thereon, means for adjusting said beds vertically in the supporting-frame, longitudinal side rails on said frame, a transfer-cylinder having suitable end cushions engaging said side rails, means for vertically adjusting said side rails so as to raise said cylinder out on contact with the printing-surface where it is desired, and means for guiding the cylinder in its motion over the frame so as to take up the impression from the stone, aluminium, or zinc plate or any other printing-surface supported on one bed and transfer it on the cardboard sheet or other article on the second bed.

The invention consists,further,of a transfercylinder hand-press in which the frame is provided with guide rails and racks for the transfer-cylinder and with vertically-adjustable side rails and mechanism for raising' or lowering said side rails so that the transfer-cylinder on its return after the impression has been transferred is raised above the printing-surface without coming in contact therewith.

The invention co1'1sists,further,of certain additional details of construction, which will be fully described hereinafter and iinall y pointed out in the claims.

In the accompanying drawings, Figure lis a side elevation of my improved transfer-cylinder hand-press. Fig. 2 is a plan view of Fig. l, and Fig. 3 is an end elevation taken from the right-hand end of the press.

Similar letters of reference indicate corresponding parts throughout the several views.

Referring to the drawings, A designates the supporting-frame of my improved transfer'- cylinder hand-press, which is composed of two longitudinal side frames connected by transverse connecting-bolts a and transverse staybars a'. Between the longitudinal side frames A are supported two beds B B', which are capable of vertical adjustment in the supportingframe by means of vertical screws (l, which turn in lugs on the bed and which rest on the lugs Pof the stay-bars a, as shown in Fig. 1. Bymeans of the adjusting-screws (Z each bed can be vertically adjusted-the bed B for the thickness of the stone, aluminium, or Zinc plate or other printing-surface which is placed thereon, so that the printing-surface of the same is brought in line with the upper edge of the side rails of the side frames in such amanner that the transfer-cylinder properly contacts with the bed B for providing for the thickness of the cardboard sheet,wood, metal, Celluloid, or other plate on which the transfer is to be accomplished. The bed is also capable of adjustment in horizontal direction by means of set-screws e, which pass through interior-l ythreaded holes of the bed and permit the hori- Zontal adjustment of the bed within certain limits, so as to place the printing-surfacc of the bed in proper relative position toward the transfer-cylinder. AThe ends of the longitudinal side frames A are provided with raised cushions f, having arc-shaped faces against which abut the cylindrical ends of the transfer-cylinder C, the ends of which are movable over the upper edges of the side frames from one end of the same to the other when making the transfer from the printing-surface to the plate or sheet to be printed. The transfercylinder C is also provided adjacent to the cylindrical ends with pinions g, which mesh with rack-bars g, attached to the outside of the side frames by bolts or in any suitable manner, the teeth of the rack projecting sufficiently alcove the upper edge of the side frame so as to permit the proper intermeshing with the pinions g at the ends of the transfer-cylinder C. The transfer-cylinder is covered at its circumference with the usual rubber blanket, by means of which the transfer of the color is made, said blanket being stretched around the cylinder b v suitable tightening mechanism that is locked after adjustment by a suitable pawland-ratchet device, as shown in Fig. l. Adjacent to the pinions g and outside of the same are arranged disks g2, which are attached to the cylinder by suitable fastening-bolts, the circumference of said disks extending midway over the teeth of the pinions, so that when the transfer-cylinder is returned from the lefthand end of the supporting-frame to the righthand end of the same by means of the handles /L after the printing is accomplished the end disks g2 are engaged by vertically-adjustable side rails fr, which are guided by slots on stationary stud -bolts on the side frames, said guide-rails being slightly inclined at their ends and raised or lowered by means of cams t, having short faces at different distances from the pivot-shaft. The upper edges of the side rails r extend over the median line of the teeth of the racks arranged alongside of the side frames, so that thecontact of the end disks g2 of the transfer-cylinder with the edges of the side rails lifts the transfer-cylinder above the surface of the stone or other printing surface that is supported on the bed B when the transfer-cylinder is returned to its initial position. The disks g3, arranged contiguously to the gear-wheels g, normally engage the top edges of the side frames and eiiiciently guide the cylinder C over the beds B B. The eccentric cam-shafts y are operated by a hand-crank 7L, that is keyed at one of said shafts at both ends of the same, preferably the one located at the middle of the supporting-frame A, said shaft being connected by cranks m and connectingrods n with two cranks on. the shaft of the second pair of eccentrics, as shown clearly in Fig. l. The second face on the eccentric, which is at a less distance from the axis of the pivotshaft of the eccentric, is placed in contact with the rails by turning the crank in downward direction, whereby the side rails are lowered so that their edges clear the teeth of the rackbars and the pinions on the transfer-cylinder can be placed in full mesh with the rack-bars. The blanket on the transfer-cylinder thus comes in contact with the printing-surface of the stone or other printing-surface supported on the bed B and the impression is properlyY transferred.

The operation of my improved transfer-cylinder hand-press is as follows: Afterl the stone, aluminium, Zinc-plate, or any other printingsurface supported on the bed B is inked in with the proper color the transfer-cylinder is rolled by hand over the surface of the same, so that the color is taken up by the rubber blanket on the ltransfer-cylinder` by rolling it over the printing-plate. The motion of the transfer-cylinder is then continued, so that it moves over the cardboard sheet, metal plate, piece of wood, Celluloid, or other surface to be printed and transfers the color taken up from the printing-surface directly to the article to be printed. After the impression is made the side rails are raised by turning the handle-of the operating mechanism in upward direction into position shown in Fig. 1, so that the disks g2 at the ends of the transfercylinder are made to move over the upper edges of the side rails of the supporting-frame y until the transfer-cylinder is returned to the cushions at the ends of the supporting side frames. During this return motion the surface of the rubber blanket on the transfer-cylinder is raised above the-printing-surface, so that no color can be taken up by the same., The side rails are then lowered again by moving the operating-crank in downward direction and placing the 'side rails on the second surface of the eccentric, which is closer to the pivots of the eccentrics, so that the next motion of the transfer-cylinder places its rubber blanket again in contact with the face of the printing-surface, so as to take up the color from the same and transfer it to the next sheet, plate, or other article to be printed on the second bed B', and so on. After theI sheet or plate is printed it is removed before the transfer-cylinder is returned again to its initial position. `During the return motion care has to be taken that the lifting side bars are raised so as to raise the transfer-cylinder out of contact with the stone or other printingsurface during its return motion, so as to prevent any possible unevenness` or doubling in the print which might be caused if the transfer-cylinder were in contact with the printing surface during its return movement. When a large number of impressions have to be made, the press can be operated by the application of power to the transfer-cylinder in such a way as to cause its movement over the beds.

My improved transfer-printing press can be used for printing from stone or other printing-surface which can be raised or lowered with its supporting-bed, so as to make up for the difference in the height of the printingsurface, the latter being always brought to the proper level for taking up the color. In

the same manner the bed which supports the article to be printed is also vertically adjusted, so that the bed can be lowered so as to print on a board one inch thick, if necessary, or on the thinnest sheet of paper or metal.

`which printed from the stone direct and which could not be used on the regular tin-printing presses without transferring twice or taking an impression from the stone first and then transferring from one sheet of paper to another sheet before laying it on the stone ready for printing.
